[PATCH 0/8] mkefidisk updates and gummiboot support

[Darren Hart]

mkefidisk was in need of some improvements. This adds gummiboot support, but
also adds improved logging, output formatting, robustness, error trapping,
cleanup, and verbosity control.

The following changes since commit 03c6fd0caab0ea8dcc2e0c3ab827a287a4f36910:

  ltp: use "foreign" automake strictness (2014-07-16 10:31:17 +0100)

[PATCH 3/8] mkefidisk.sh: Add gummiboot support

[Darren Hart]

Fixes [YOCTO 6295]

Add gummiboot support for images built using:

EFI_PROVIDER="gummiboot"

Add conditional configuration for GRUB and gummiboot. Provide some
messaging about which is being performed.

[PATCH 4/8] mkefidisk.sh: Copy the EFI dir recursively

[Darren Hart]

Rather than only copying the EFI/BOOT dir, copy the entire EFI dir
recursively. This allows for custom configurations to be enabled
implicitly with no extra work required.

[PATCH 5/8] mkefidisk.sh: Improve logging

[Darren Hart]

Add logging functions: error, warn, info, and success, using tput to add
color highlighting.

Use these routines throughout the script, replacing echo statements and
adding "|| error" in several places to eliminate silent failures. Add a
simple exit block which checks for issues encountered while running.

[PATCH 6/8] mkefidisk.sh: Add die() and cleanup() routines

[Darren Hart]

Currently the script will attempt to continue even after a fatal error.
Add a die() routine which will abort in the case of a fatal error and
call a cleanup() routine to unmount any images or devices and remove the
TMPDIR.

Move the variable assignment and directory creation earlier in the
script, making it more obvious what we need to clean up.
